If you uploaded today and got an upload that showed '0 bytes' in the end, it's because we ran out of space. Use the 'update' feature, or delete, and re-upload (will require a file name change).
I've freed up a little space, to last us for a bit, but I'll have to scrounge for any more, out of cash, and no time to 'upgrade' the old system.
The new system will be improved (more space, easier to upgrade), but I'm lacking the funds at the moment...
